RAlLROAD-RAlL-GUARD CLAMP.

SPECIFICATION forming part of Letters Patent No. 787,186, dated April11, 1905.

Application tiled October 3,1904. Serial No. 226.893.

Be it known that I, Fanvuw H. JOIIXSWJN, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful liailroadRaildluard Clamp, of which thefollowing is a specification.

My invention relates to guards for railroadrails: and it consists of anovel clamp for the same, as will be hereinafter described.

Figure I represents an end elevation of a clamp for a guard-railembodying my invention. Fig. 2 represents a top or plan viewof the same.

Similar letters of reference indicate corresponding parts in theligures.

Referring to the drawings, A designates a railroznlaail, and Bdesignates a guard-rail therefor.

L designates a filling-piece which is interposed between the oppositesides of said rails A and B and rested upon the flanges thereof, theyserving to retain said rails the proper distance apart.

I) designates a clamp which consists of the base I l, the sides F on theouter ends thereof, and the lips (i, which are inturned from the upperends of said sides F, the inner walls of the latter being tapering, asshown dotted in Fig.

H designates cheek-pieces which are interposed between the sides F ofthe clamp and the sides of the rails A B and rest on the outer flangesof said rails and the adjacent portions of base IQ, they being alsoembraced on top by the lips (I, so as to be prevented from rising. Theouter sides of the cheek-pieces are tapering and engage with thetapering inner walls of the sides F, it being seen that when thecheek-pieces are driven up there is a wedging action of the same withthe sides F, and thus they are forcibly pressed against the rails, thelatter thus being most lirmly clamped without the use of bolts, spikes,&c.

In order to prevent return motions of the cheek-pieces or of the clamp,said pieces are formed with a seriesof vertical openings J near thenarrow end of said pieces, which openings receive the pins K, whichengage with the adjacent ends of lips (I, as in Fig. 2, and interlocksaid cheek-pieces with said lips, and consequently with the clamp, theeli'ect of which is evident. The lower ends of the pins Ii are split, soas to be prevented from rising and improper displacement.

In order to prevent longitudinal shiflingof the filling-piece (1,vertical openings L are formed in the same to receive the pins M, whichalso enter openings N in the base E, it being noticed that theinner sideof the flange of the rail B is cut away, as at I", forming a spacebetween the flanges of the two rails, through which the pins M. passfrom the piece G into said base F.

It is evident that when the pins K are withdrawn the cheek-pieces may beloosened or moved to release the same of the holding actions of theclamps and be entirely displaced. 'hen the pins M are withdrawn, thelillingpiece 0 is free to be withdrawn. A stud L on the piece 0 entersthe respective opening L in the webs for additionally locking said piecewhen so required.

Various changes may be made in the details of construction shown withoutdeparting from the general spirit of my invention, and I do not,therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a guard-rail clamp, a clamp having a side member, an inturned topmember and a base member, a cheek-piece resting on said base member andembraced by said side and top members, said cheel piece having anopening therein and being adapted to contact with the side of a rail,means for imparting pressure to said cheek-piece laterally against said,rail and a pin adapted to enter said opening and engage a member ofsaid clamp for preventing disengaging movement of said cheekpiece.

2. In a guard-rail clamp, a. clamp having a side member, an inturned topmember and a base member and a cheek-piece resting on said base memberand embraced by said side and top members, said cheek-piece having anopening therein being adapted to contact with the side of a rail, theplaces of side contact of said clamp and cheek-piece being wedging and apin adapted to enter said opening and engage with the member of saidclamp.

3. A clamp for a guard-rail having a base, a side piece and a topinturned lip, a checkpiece adapted to be interposed between said sideand the rail and provided with a series of openings, said side and cheekpieces having wedging contact-surfaces and a pin adapted to fit ineither of said openings and engage a member of said clamp.

4. A railroad-rail and a guard-rail, a filling-piece between said rails,cheek-pieces on the outer sides of the webs of said rails, a clamphaving side members adapted to wedge with said cheek-piece and forciblyhold the same against the rails, and means on said filling-piece andrail for interlocking said piece with said rail.

5. A railroad-rail and a guard-rail and a clamp therefor composed of abase on which said rails rest, sides rising from said base and inturnedlips at the top of said sides, said lips embracing the upper faces ofsaid cheek-pieces and said sides and cheek-pieces having wedgingcontact-surfaces, means for interlocking said filling-piece with thebase of said clamp and a pin adapted to enter said cheek-piece andengage the adjacent memberof said clamp.

6. In a guard-rail clamp, a cheek-piece havpering sides, said sidescontacting with said cheek-piece and the latter bearing against the sideof the rail, a filling-piece between the rails and means forinterlocking said piece with the base of said clamp, the flanges of therails having a channel between them for the passage of said meanstherethrough.

7. In a guard-rail clamp, a clamp having a side member, an inturned topmember and a base member, a cheek-piece resting on said base member andembraced by said side and top members, said cheek-piece being adapted tocontact with the side of a rail, means for imparting pressure to saidcheek-piece laterally against said rail, and an opening in saidcheek-piece and a pin in said opening engaging the adjacent member ofsaid clamp for preventing releasing motion of said checkpiece.

8. In a guard-rail clamp, a filling-piece, a laterally-projecting studon said piece and a rail havinga recess in the side of its web, saidstud being adapted to enter said recess and thereby interlock said piecewith said rail.
